The DS-7732NXI-K4 is a 1.5U NVR designed for medium to large installations. With up to 12 MP decoding, it handles very high resolution video streams ensuring quality and smoothness in even the most demanding applications. With up to 256 Mbps of input bandwidth, it supports the latest generation of cameras without bottlenecks.
Using AcuSense technology, this NVR integrates advanced video analytics to dramatically reduce false alarms caused by irrelevant movements (rain, animals, leaves). AI features include:
Facial recognition with image comparison and search
Intelligent perimeter to distinguish people and vehicles
Motion Detection 2.0 with subject classification (human/vehicle)
The unit handles two-way audio, supports numerous codecs (AAC, G.711, G.722) and offers independent 4K HDMI and VGA outputs. Network connectivity is provided by 2 Gigabit RJ-45 ports, while USB 2.0 and 3.0 ports simplify backups and upgrades.
